SPEC'FICATION forming part of Letters Patent No. 451,537, dated 'May 5, 1891.

Application tiled May 12, 1890.

Serial No. 351,483. (No model.)

To all whom it' may concern.'

Be it known that I, JOHN H. VAIT, a citizen of the United States, residing at Portsmouth, in the county of Sciota and State of Ohio, have invented a new and useful Stench- Trap, of which the following is a specification.

This invention relates to water-closets and slop-pails, and more especially to the stench traps used therein; and the object of the invention is to provide a device which will prevent the escape of offensive odors, its construction being,l an improvement on devices of this general character heretofore existing.

To this end the invention consists of a receptacle having below its open upper end or mouth an annular flange into which is passed a closing-plug having a trap therein of peculiar construction, all as will be hereinafter more fully described, and illustrated. in the drawings, in which Figure 1 is a central vertical section of an ordinary slop-pail with my improvements attached. Fig. 2 is a side elevation, and Fig. 3 is a section, of one form of plug embodying my invention, the receptacle being shown in dotted lines. Figs. 4 and 5 are respectively a side elevation and section of another form of plug.

Referring to the said drawings, the letter R designates a receptacle, such as an ordinary slop-pail or a public urinal or com- Inode U.

The former is provided with au interior upwardly-extending flange F below its open upper end, which may receive an ordinary cover, if desired, or may be left open. C is the cover referred to, preferably convex, and having a depending annular flange c, adapted to pass into and loosely it the groove in the iiange F, as shown in Fig. 1, said cover being preferably provided with a handle H, whereby it can be removed when it is desired to use the receptacle for other purposes than urinating therein, or when it is desired to empty the contents therefrom. This cover being applied in place with its depending flange c seated in the grooved flange F, if urine or other water be poured upon the convex upper face of the cover it will run down to the periphery of the same and into the groove of the ange F, which it will fill to above the level of the lower edge of the depending flange c, thereby forming a water seal between the parts and preventing the escape of offensive odors from the interior of the receptacle, as will be clearly understood. Although I have shown and described this cover C, l prefer to use a plug for closing the vessel.'

In Figs. 2 to 5 l have shown different forms of plugs which may be used, and these plugs may be of such asize as to be placed directly within the openings in the flange F of the receptacle R, (shown in Fig. 1,) which they will close tightly, as will be understood.

The plug shown in Figs. 3 and 11 consists of a tapered body T, having a handle H atits upper end. This body is provided with a lateral opening O at one side and at such point that it will stand below the flange F, and a central passa-gel? extends downwardly from the upper end of the body nearly to the lower end of the plug, and then turns upwardly into and opens out through the opening O. The urine in this case would flow down such passage and fill the lower end thereof, overilowing through the opening O, and a perfect stenclrtrap would be formed thereby, the plug being removed when it was desired to use the receptacle for other purposes.

In the construction illustrated in Figs. 5 and 6 the tapered portion of the body T of the plug has a reduced and rounded lower end F., and the passage l? extends vertically through the body and end, as shown. The lower portion of the bodyL has a cup-shaped upper end open at each side, as at O,between upwardly-extending ears e, the upper edges of the cup being higher than the lower end of the passage through the end E. The ears e are pivotally connected with the end E, whereby the lower portion L of the plug can be detached for cleaning. This construction of plug is especially useful in connection with portable receptacles R,because when such receptacles are carried from place to place they are likely to be tilted slightly, whereby the water seal in the grooved flange F or in the opening O of the solid plug would be spilled and' would flow into the body of the receptacle. This spilling would destroy the efficiency of the trap and allow offensive odors to escape,

member thereof would swing from side to side and aperfect seal would always be main- ICO whereas with this two-part plug the lower tained while the receptacle was being carried about,as will be understood.

I elaiin as the salient points of this inventionl. In a commode, the combination, with the receptacle having an interior annular flange below its upperend, of a plug havinga tapered body tightly ittin gin said flange, said body be ing provided with a passage extending downwardly from its upper end and terminating in an open eu p which proj eets above the lower end of the opening, so as to forrn a seal therefor, and finally opening at the side ot' the plug below7 the flange, as and for the purpose set forth.

2. In a eolnmode, the combination, with the receptacle having an interior annular flange below its upper end, of a plug having a tapered body at its upper portion tightly iittin g said flange, the lower end of said body being reduced, said body and lower end being provided with a vertical passage, and a lower portion of said body having a cup-shaped upper end, with ears thereon pivoted to said lower end of the upper portion, the upper edges of the eup standing above the lower end of the said passage and below the flange in the receptacle, all as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto ailixed my signature in presence of two witnesses.
